Mars: upper atmosphere.
The thermal structure of the upper atmosphere of Mars has been theoretically investigated. The exospheric temperature, for a pure CO(2) model atmosphere, lies between 400 degrees and 700 degrees K. The origin of the Martian atmosphere is discussed in the light of these results.
متن کاملWaves in Pluto’s Upper Atmosphere
Observations of the 2007 March 18 occultation of the star P445.3 (2UCAC 25823784; R = 15.3) by Pluto were obtained at high time resolution at five sites across the western United States and reduced to produce light curves for each station using standard aperture photometry. Global models of Pluto’s upper atmosphere are fitted simultaneously to all resulting light curves. The results of these mo...
متن کاملNonlinear internal waves in the upper atmosphere
This paper considers the large-scale dynamics generated in the upper atmosphere by the destabilization of a linear internal gravity wave and its eventual restabilization through nonlinear processes into a coherent pattern. The assumption of a strongly dissipative medium is relevant to wave propagation in the thermosphere range above 100 km. A parametric instability analysis is carried out invol...
متن کاملEffects of Tsunamis on the Upper Atmosphere
Following the early suggestion of Peltier and Hines [1], it is now generally accepted that tsunamis can excite acoustic-gravity waves, and that these waves can propagate to the upper atmosphere. Because of the decrease of atmospheric density with increasing altitude, conservation of wave energy causes the wave disturbance amplitudes to increase with increasing altitude. At high altitudes molecu...
متن کاملInfrared Scattering Observations in the Upper Atmosphere
Observations of sky emission and absorption in the far infrared (mean wavelength 120 /•) and, simultaneously, sky emission at wavelength 6 • have been made by P. Kuhn (ESSA): from the NASA CV-990 aircraft flying at 12-km altitude over the middle Pacific at latitudes 10ø-15øN. A lack of correlation between the nearand far-infrared data, especially during times of visible cirrus cloud cover above...
